Hi Ronn--
A similar question to this was asked a few months ago. No really deep
technical discussions ensued, but this was the gist of it:
* I advocated astronomy's FITS format. Plus: platform independent,
metadata is in ASCII, good support in IDL Astronomy Library. Minus:
seen as "archane."
* I also advocated IDL SAVE files. With my library you can read and
write SAVE files sequentially like any other file. Plus: native to
IDL. Minus: tied to IDL.
* Many people seem to swear by Liam Gumley's binary tools. Plus: raw
speed and direct access; platform neutral. Minus: low level.
* Martin Schultz advocated GRIB, half tongue in cheek.
As I said, no real answers came out of this, but at least it may give
you some other ideas.
